Answer:
70
Step-by-step explanation:
You know the fourth number in this pattern is 15, and that they are all consecutive. With this information you know that the fifth number will be 16, and by counting backwards from 15 you can figure out all of the numbers are 12, 13, 14, 15, and 16. Now, to find the sum of these numbers you must add them together.
This is what it could look like: 12+13+14+15+16
Now to find the answer you need to calculate what the addition would equal, which is 70.
1. 12=x+3 12-3=9 now try 9+3 that is 12 so x=9
2. b+0.6=-1 -1-0.6=-1.6 -1.6+0.6=-1 b=-1.6
3. a=-9
4. x=-39 I believe
5. a=-4.3
Answer:
Alfonso will need to work 8 hours. What i did was multiply 8 by 6 which is 48 then subtracted 48 by 144 and got 96 then you divide that by 12 which is 8, and that is how many hours he will have to work.

Answer:
16.4%
Step-by-step explanation:
Assuming the 5% was taken off of the already-discounted price, then the original price was multiplied by ...
(1 -12%)(1 -5%) = 0.88×0.95 = 0.836 = 1 -16.4%
The total decrease was 16.4%.
